3.7 or 3.9 diff gears will see you next to commodores off the line.

Anything is possible, how much you willing to pay. I've already thought about this, and after asking around dismissed it due to cost involved. Get a T5 or a much better diff ratio.

Oh, change the the same 1 and 2nd ratio from a commie, leave 3rd and 4th the same, so you get to keep some form of fuel economy.

Sure do, I really cant see anyone swapping the gears. Even if it was possible, it would be FAR cheaper just to use a commy box with a CRS bellhousing.

Not sure. I was quoted $1150 for a kit to put a T400 behind a 4.0 so probably somewhere around there.

Worth it? Good question.

For the same price you could put a t5 in.
